How to concatenate all the array elements except the first one, using Bash?-CodePudding

InputList="Item1,Item2,Item3,....,ItemN"

Desired output:

NewList1="Item1"

NewList2="Item2;Item3;....;ItemN"

Note that the separator of the original input list is a , (comma) whereas that of the new lists is a ; (semicolon).

Please suggest a suitable Bash script. Thanks.

With bash and its Parameter Expansion:

List1="Item1"
List2="Item2;Item3;....;ItemN"

List1="${InputArray%%,*}"

List2="${InputArray#*,}"
List2="${List2//,/;}"

echo "$List1"
echo "$List2"

Output:

Item1
Item2;Item3;....;ItemN
